A look inside the cabins of Amtrak’s new Acela Express cars.

At an event in Wilmington last week, Amtrak demonstrated the interior features of its new Acela train cars, which utilize principles of universal design to boost accessibility for people with and without disabilities. Modifications include grab bars in aisles for stability, lighter tray tables, high-resolution LCD signage and more spacious bathrooms. The train cars will be introduced in 2021.
